[Kinako Yakumo] My First Time Is With My Brother A Pure Sister Gets Corrupted Volume 1-2 [Decensored]

An innocent sister's first time belongs to the one man who refuses to let anyone else have it—her own brother. He peels away her lace and her composure in equal measure, teasing her until she's weak everywhere and shamefully wet, then punishing her when another man's voice stirs something she shouldn't feel. Across two chapters, her protests dissolve under his relentless hands as stiff nipples and slick heat confess what her trembling voice never could.
